## EXECUTIVE SUMMARY
IP 54.39.0.212 is a cloud infrastructure endpoint hosted on OVH (ASN 16276) within the 54.39.0.0/24 subnet. While the individual IP presents a moderate risk profile (risk score: 40), the subnet demonstrates elevated threat activity with a 71.88% abuse density classification. No direct threat indicators were observed, but contextual neighborhood risk warrants defensive consideration.

## OWNERSHIP & GEOLOCATION
| Attribute | Value |
|---|---|
| **ASN** | 16276 (OVH) |
| **Organization** | Dmytro, Ahrefs Pte Ltd |
| **Network Block** | 54.39.0.0/24 |
| **RIR** | ARIN |
| **Geolocation** | Canada, Quebec, Beaucharnois |
| **Infrastructure Type** | Cloud Compute |
| **Hosting Status** | Active |
Geolocation Validation: INCONSISTENT. RTT measurements indicate 30ms latency with a 5,629km distance claim, creating a 112.6ms minimum RTT violation. This suggests potential geolocation spoofing or data inconsistency requiring validation.

## THREAT PROFILE
| Indicator | Status |
|---|---|
| **Known Attacker** | No |
| **Tor Exit Node** | No |
| **Spam Source** | No |
| **Blacklist Count** | 0 |
| **DNSBL Listed** | 1 of 8 lists |
| **Campaign Likelihood** | None |
Threat Signals: No active threat indicators detected. No known malware campaigns, attacker signatures, or spam associations observed.

## NEIGHBORHOOD ANALYSIS
The 54.39.0.0/24 subnet shows significant threat concentration:
| Metric | Value |
|---|---|
| **Abuse Density** | 71.88% |
| **Subnet Classification** | High Abuse |
| **Total Siblings** | 256 |
| **Active Siblings** | 227 |
| **Threat Siblings** | 184 |
| **Inherited Risk Score** | 28 |
Risk Context: This subnet's elevated abuse density (71.88%) indicates that threat activity is concentrated within the broader network segment. While the target IP lacks direct indicators, the neighborhood context suggests potential for coordinated or shared infrastructure misuse.
---
## DNS & SERVICES
| Attribute | Value |
|---|---|
| **PTR Hostname** | proxy-ca004-san212.ahrefs.net |
| **Forward Confirmed** | No |
| **Hosted Domain** | ahrefs.net |
| **Open Ports** | None detected |
| **Service Status** | Firewall / No Services |
DNS Validation: Reverse DNS records exist but forward resolution is unconfirmed, indicating the IP may be in a non-public-facing or internal network segment.
---
## OBSERVATION HISTORY
Recent monitoring activity (20 observations) shows:
- Consistent Classification: High-abuse neighborhood designation maintained across observation period
- Geolocation Data: Multiple conflicting geolocation reports with varying confidence levels
- Threat Persistence: No persistent malicious activity observed (0 threat observation days)
---
## RECOMMENDED ACTIONS
Based on the moderate risk score and high-abuse neighborhood context:
Firewall Recommendations:
```bash
# iptables
iptables -A INPUT -s 54.39.0.212 -j DROP
# nftables
nft add rule inet filter input ip saddr 54.39.0.212 drop
# nginx
deny 54.39.0.212;
```
WAF/CDN Integration:
- Cloudflare WAF: Block rule with description "IPDebrief risk 40"
- AWS WAF: Add 54.39.0.212/32 to IP block list
Implementation Note: Consider implementing subnet-level monitoring or blocking (54.39.0.0/24) given the 71.88% abuse density, though this should be weighed against potential false positives from legitimate cloud infrastructure.
---
## ANALYST NOTES
1. Context-Aware Risk: While the IP shows moderate risk individually, the subnet's high abuse density suggests broader infrastructure concerns.
2. Geolocation Inconsistencies: RTT violations warrant periodic revalidation of geolocation data.
3. Cloud Infrastructure: No direct services or open ports detectedβtypical of cloud compute environments.
4. Monitoring Recommendation: Track subnet-level activity patterns to identify coordinated threats.
